RE: [PHP-PEAR] DB backend status

Hello ! Could anyone explain me what a "regression test" is. I'm considering PEAR's DB backends among others like PHPLIB for use in a project using MySQL and problably Postgress in the future.I'd like to know whether it is important (in terms of stability) or not to use a DB backend that has gone through this stage.
